Hello,

I want to know if it is ok if I use links in one of the subdirectories of my $EPREFIX.

Something like:

/shared-nfs-location/local/solaris-i386/gentoo-prefix/ -> gentoo-prefix.prod

The reason is that I have everything on a shared NFS, for all servers (I know it is not a good idea, but it is how they have it installed) and I want to be able to compile critical stuff (like perl, gcc) in other location before apply the changes in the shared location.

My main problem is that I have already everyhing in the shared nfs location, and I do not want to recompile everything now.

My idea is do this when I need to recompile something:

/shared-nfs-location/local/solaris-i386/gentoo-prefix/ -> /local-location/gentoo-prefix
/local-location/gentoo-prefix -> /shared-nfs-location/local/solaris-i386/gentoo-prefix-testing/

Will I have problems if I use links? Maybe some packages compute their real location.

Some packages have hardcoded paths in their files and will break if you use symlinks.

You can use binpkgs to transfer packages between prefixes, with some restrictions (build ${EPREFIX} must be of longer or equal length to install ${EPREFIX})

also, gcc doesn't like symlinks, and will compute the real path in use (following the symlinks)
